A NEW GENUS AND SPECIES OF AUSTRALIAN EESPERIAD.'E. 

 Br E. MEYIUCK, U.A., F.Z.S. 



Tn Watson's revision of o;eiiei'a of the Hesperiadce (Proc. Zool. 

 See. Lond., 1893, pp. o — 132) several Australian genera are indicated, 

 allied to Telesfo, whicli I regard as insufficiently grounded and not 

 truly separable from tliat genus, being based on differences of antennal 

 structure which are only comparative and vary specifically (and even 

 to some extent individually). Motasinr/hd, Wats , HesperUla, Hew., 

 and Pathisin(/]ia, Wats, (beside others indicated as distinct, but not 

 named), ni-e thus in my judgment untenable. The following genus, 

 liowever, iippears lo be truly distinct, bolh structurallv and su|)ei'fici- 

 ally. 

 Mesodina, )/. g. 



Club of antpiina^ clong.ito, ])oint.e(l, bent. Palpi obliqunly asrc-iidiiifT, teriviiiial 

 joint very sliort. Posterior libia; without middle spur.i. Fore-wings in ^ without 

 stigma ; vein 5 parallel to 4 and 6, slightly nearer to f! at base. Ilind-wings with 

 vein 5 obsolete. 



Nearly allied to Trapezites and TeJcsto, but differing from both 

 in the absence of the middle s|)urs of the posterior 1ibia>. Type, M. 

 liali/zit), Hew. liesides tht^ fyj"" 1 know only the following new 

 species : — 

 M. jELtjropis, n. sp. 



g 36 inm. Head, thorax, and abdomen dark fuscous. Fore-wings rather 

 elongate-triangular, eosta subsinuate, ternien gentl}' rountled, sliglitlj oblique ; dark 

 brown, becoming dark fuscous towards costa, with some yellowi^i hairs anteriorly 

 on dorsal half; a ti-apczoidal light oehreous-yellowish blotch occui^jing posterior 

 end of cell, broadest beneath ; a transverse angular light oehreous-yellowish bloteli 

 between veins 2 — 4, cut by vein 3, its upper angle nearly touching lower angle of 

 ]ireeeding blotch ; three very obscurely indicated i)ale yellowish dots placed in a 

 straight transverse series between veins 6 — 9, slightly nearer cell than apes : cilia 

 fuscous, basal half darker. Hind-wings with (ernien strongly ruundcti ; dark brown, 

 slightly coppery-tinged, especially in disc ; hairs in disc yellow ; an undefined spot 

 of scattered yellowish scales in disc beyond cell. Fore-wings beneath fuscous, 

 becoming dark fuscous in disc, sprinkled with pale greyish scales towards upper half 

 of termen ; discal blotches as above, but rest of cell filled with deep yellow. Hind- 

 wings beneath fuscous, densely irrorated with whitish-grey ; thfc absence of irrora- 

 tion forms a postmedian series of tlu'ee obscure roundish spots between veins 

 16—4..
